In a large mixing bowl combine cake mix, oil, eggs, and vanilla extract.
Place dough in the fridge to chill for 30 minutes to 1 hour.
Preheat your oven to 350 degrees. Prepare a baking dish with parchment paper.
Roll cooking dough into balls then roll them in sugar and place on your prepared baking sheet. Top cookies with sprinkles and bake for 9-10 minutes. Allow to cool for 1 minute on the baking sheet then remove and cool completely on a cooling rack.
Tip: Change your sprinkle colors for a theme or festive cookies.
